CHANNELEB. FOR AWLS.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed September 9, 1911. Serial No. 648,558.

To all whom it may concern.

Be it known that I, James D. RANDALL, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Channelers for Awls, of which the following is a specification.

My invention relates to a channeler for use in sewing machines adapted to stitch heavy material such as leather, rubber, etc.

The function of the channeler is to form a groove or out between the holes which are formed by the awl, the groove being to receive the thread between the holes so as to submerge or bury the stitching.

The object of my invention is a channeler of simple construction which will remain firmly in line with the stitching and may be attached readily in place for use.

In the accompanying drawings, I have illustrated a channeler embodying my invention and have illustrated it in connection with the parts of the sewing machine necessary to illustrate its connection therewith.

Figure 1 is an elevation of parts of a sewing machine and of the channeler embodying my invention. Fig. 2 is a view in elevation of my channeler, in combination with an awl. Fig. 3 is a view taken at right angles to Fig. 2. Fig. 4: is a perspective view of the channeler embodying my invention.

Referring to the parts: My channeler is used in combination with the usual awl B. The awl B punches the usual holes in the material D for the passage of the needle E, the foot 6 holding the material intermittently in place while the needle is forming Gopies of this patent may be, obtained for the loop. The material is fed beneath the awl so that it makes a series of holes in the material.

The channeler embodying my invention comprises a spur having at its lower end a wedge-shaped cutting edge a, and having near its upper end a collar a projecting transversely from the spur, and having a longitudinal bore a and a transverse bore a*, to receive a set screw (6 for fastening the channeler upon the awl. The wedgeshaped cutting edge a is made at least of a width equal to the distance between the holes which are punched by the awl B. The bore a is of a diameter such'as to permit the collar a to be slipped over the awl B.

In use: The collar a being placed over the awl and the set screw a being tightened, the channeler is held firmly in alinement with the row of stitching. The operation of securing the channeler upon the awl is a simple one and it may be adjusted readily upon the awl, to vary the depth of the channcl which is made by it.

What I claim is:

The combination of an awl and a chan neler consisting of a spur, a collar projecting from one side of the spur and having sliding connection with the awl, and a set screw extending through the collar and adapted to engage the awl for locking the channeler in any desired position upon the awl.
